DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0018] Referring to the drawings, and initially to FIGS. 1 and 2, an exerciser in accordance with the present invention comprises a stem 10 including a bar 11 provided on one end thereof, for engaging onto the abdominal portion of a user 70 (FIG. 3), and a housing 14 provided on the other end thereof. For example, the bar 11 includes a curved recess or surface 19 formed therein for comfortably engaging onto the abdominal portion of the user 70.

[0019] One or more, such as two handgrips 12 are attached to the stem 10, and disposed on the opposite sides of the stem 10, and/or attached or secured between the stem 10 and the housing 14, for forming a substantially U-shaped handle 13. It is preferable that a reduced diameter portion or neck portion 17 is formed between the housing 14 and the respective the stem 10 and the handgrips 12 or the handle 13.

[0020] Each of the stem 10 and the handle 13 or the handgrips 12 includes a hollow interior or passage 15 formed therein and communicating with each other. The housing 14 is preferably spherical having a chamber 16, such as a circular or spherical chamber 16 formed therein and communicating with the passage 15 of the stem 10 and the handle 13 or the handgrips 12. The stem 10 and the handle 13 and the housing 14 may be formed by such as molding or blow molding processes.

[0021] A weight 20 is movably received in the chamber 16 of the housing 14, and includes a core 21 made of heavier materials, such as metal, and an outer covering 23 provided on the outer peripheral portion of the core 21 with such as molding or mold injection processes. It is preferable that the weight 20 includes one or more grooves or cavities 24 and/or projections 27 formed or provided on the outer peripheral portion of the outer cover 23, for generating vibrations when the weight 20 is moved against the inner peripheral surface 18 of the housing 14.

[0022] It is to be noted that the weight 20 may be formed and disposed within a mold cavity of a mold device (not shown) before blow molding the stem 10 and the housing 14. Alternatively, the stem 10 and the housing 14 and/or the handgrips 12 may include two halves first formed, and then dispose the weight 20 into the chamber 16 of the housing 14, and then secure or mold the two halves of the stem 10 and the housing 14 and/or the handgrips 12 together.

[0023] In operation, as shown in FIG. 3, the user may hold the exerciser by grasping the handgrips 12 or the handle 13, or by grasping the stem 10, and may then engage the one end or the bar 11 with his abdominal portion, the chest portion, or the other portions. The user may then swing his body, in order to move the weight 20 along or against the inner peripheral surface 18 of the housing 14, and to train his waist portion or abdominal portion.

[0024] When the weight 20 is moved or rotated against the inner peripheral surface 18 of the housing 14, the weight 20 may apply forces against the abdominal portion, the chest portion, or the other portions of the user periodically in order to massage the user. In addition, the engagement of the projections 27 of the weight 20 with the inner peripheral surface 18 of the housing 14 may generate vibrations in order to further massage the abdominal portion, the chest portion, or the other portions of the user.

[0025] As shown in FIG. 2, a circuit board 30 may further be disposed within the handgrips 12 or the housing 14 or the stem 10, and includes a processor device 3 1 attached thereto, one or more batteries 33 provided thereon and coupled to the processor device 31, and a probe or switch 34 attached thereon. The switch 34 includes a button 36 slightly extended into the chamber 16 of the housing 14, for engaging with the weight 20, and for counting the rotational movements of the weight 20 relative to the housing 14.

[0026] As shown in FIGS. 1 and 3, a display 37 may further be provided and disposed on the stem 10 or the handgrips 12 or the housing 14, and coupled to the processor device 31, for displaying time, and/or the counts or the number of the rotational movements of the weight 20 relative to the housing 14. The batteries 33 may be used to energize the processor device 31, the display 37, and/or the other electrical parts or elements (not shown).

[0027] Accordingly, the exerciser in accordance with the present invention may be used for allowing users to easily train their waist portions, and to massage their abdominal portions.
